In some case that delete attempt fails when +the target inode is a directory that contains a subvolume inside it, since +the log replay code is not prepared to deal with directory entries that +point to root items (only inode items). + +1) We have directories "dir1" (inode A) and "dir2" (inode B) under the + same parent directory; + +2) We have a file (inode C) under directory "dir1" (inode A); + +3) We have a subvolume inside directory "dir2" (inode B); + +4) All these inodes were persisted in a past transaction and we are + currently at transaction N; + +5) We rename the file (inode C), so at btrfs_log_new_name() we update + inode C's last_unlink_trans to N; + +6) We get a rename exchange for "dir1" (inode A) and "dir2" (inode B), + so after the exchange "dir1" is inode B and "dir2" is inode A. + During the rename exchange we call btrfs_log_new_name() for inodes + A and B, but because they are directories, we don't update their + last_unlink_trans to N; + +7) An fsync against the file (inode C) is done, and because its inode + has a last_unlink_trans with a value of N we log its parent directory + (inode A) (through btrfs_log_all_parents(), called from + btrfs_log_inode_parent()). + +8) So we end up with inode B not logged, which now has the old name + of inode A. At copy_inode_items_to_log(), when logging inode A, we + did not check if we had any conflicting inode to log because inode + A has a generation lower than the current transaction (created in + a past transaction); + +9) After a power failure, when replaying the log tree, since we find that + inode A has a new name that conflicts with the name of inode B in the + fs tree, we attempt to delete inode B... this is wrong since that + directory was never deleted before the power failure, and because there + is a subvolume inside that directory, attempting to delete it will fail + since replay_dir_deletes() and btrfs_unlink_inode() are not prepared + to deal with dir items that point to roots instead of inodes. + + When that happens the mount fails and we get a stack trace like the +
